LUBRICATOB.

To all 'whom it may concern:

Be it known that I, JACOB LLOYD WAYNE, 3d, a citizen ofthe United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Lubricators, of which the following is a specification.

In the operation of all kinds of machinery, it is essential that the bearing surfaces be kept .well lubricated. Yet the ordi-l nary lubricators are frequently located, by necessity, at places where dirt and grease accumulate on them, so that their operation is frequently very distasteful as well as di cult and there is a tendency on .the part of the operator to neglect them. This is especially true in motor cars and other power driven vehicles.

It is the object of my present invention to make the operating of a lubricator easier and less distasteful, to avoid any exposed grease which invites dirt to accumulate, and to make the handling of the supply of lubricant easy and not unpleasant.

In accomplishing this object I put up the lubricant in ,collapsible tubes, preferably provided with screw threaded discharge nozzles; and connecting these collapsible tubes' to the apertures of the lubricator cups by suchnozzles. Then by compressing the tube the lubricant may be fed to the surface to be lubricated, as required. This compression may be obtained in any desired manner, but most conveniently by a lsuitable key. When the tube is emptied a fulltube may be easily substituted forvit. The accompanying drawings illustrate my invention. Figure 1 is a sectional view of one form of the lubricator with a collapsible tube of and cold weather, the tubes maybe changed lubricant associated with it; Fig; 2 is a view showing a collapsible tube of lubricant with an extended nozzle; and Figs. 3 and 4 are sectional and plan views respectively of a grease cup with which the device shown in Fig. 2 may be removably associated.

In the arrangement shown in Fig. 1, there is a grease cup 10, which is shown as having an externally screw-threaded projection 11 by which it may be associated with the device to be lubricated, there being a duct 12 which extends through such projection 11 to con! duct the lubricant to the surfaces to be lubricated. A collapsible tube 13 for the lubricant is removably associated in any desired grease-tight mannerwithl the grease cup 10,-

Application mea April 27, 1914. serial No. 884,583; REIS so that when compressed it will discharge lubricant into and `through the aperture 12 to the surfaces to be lubricated. This tube forms a lubricant VYcontainer which is her-v` metically sealed save at thedischarge opening. In the arrangementshown the collapsible tube 13 is provided with a nozzle 14 which ts into an opening 15 at the inlet end of the duct 12, the nozzle 14 and opening 15 conveniently being screw-threadedto provide a convenient means of attachment. If desired, a washer 16 maybe placed between the collapsible -tube andthe grease cup to seal the joint more eectively. `By now compressing the tube 13 in any suitable manner, the lubricant contained therein is forced through the duct 12 to the surfaces to be lubricated. A convenient way of compressing the tube is by a key 17, which iit's over the permanently closed end of the tube in a well-known manner and when turned flattens the tube and winds it up on itself, thereby forcing out the contents of the tube. The grease cup may have associated therewith a removable cap 18 for inclosing the collapsible tube, this cap being fastened to theV grease cup in any suitable manner, as by having a spring fit over a flange 19 of the grease cup. If desired, the cap 18 may be longitudinally slotted'to receive the key 17, the slots serving as guides for the key. With this arrangement no lubricant can escape from thetube to exposed parts, so that comparative cleanliness is maintained, and the operation of the lubricator is rendered less distasteful. 'When a tube is emptied, the cap 18 may be removed, the empty tube detached, and a full tube attached in its place, and the cap 18 replaced. In case lubricant of k,different consistencies is used, as in hot without waste and with ease as desired. Practically all contact with dirt and grease is avoided both in connection with the grease cup and in dealing with the tubes. When a eoY tube is'not in use its outlet may be suitably empty', unless it is desired` to remove it sooner as for changing the tubes. Where it is not desirable to leave the collapsible tube in place the arrangement shown in Figs. 2, 3, and 4 may be used. Here instead of the slotted cap 18 of Fig. 1, a flat cap 25 is provided for the grease cup 10, for closing the latte1',and the collapsible tube-13 is put in place only when the cap is moved to expose the inlet end of the aperture of the grease cup, and is removed when the desired "amount 'of lubricant has been forced, asby the key V17, to the surface to be lubricated. lf desired, a nozzle extension 26 may be l provided for the collapsible tube, such nozzle extension conveniently having one end in the form of a socket 27 adapted to -receive the discharge endfof` the tube and the other end adapted to be associated with theiinlet end of the aperture through the grease cup and also 'to receive the cap 20. lhe nozzle extension may be of any suitable shape,

and either stiii' or flexible. This nozzle extension greatly facilitates the reaching "of the more inaccessible grease cups.

It is not necessary that the part which have called the grease cu be non-integral with the associated part o the machine havlubricated.
